-APPARATUS FOR GRANULATING BLAST-FURNACE SLAG.

Specification of Letters Patent.

Patented och-25, 1910.

Application filed February 11, 1910. Serial No. 543,389.

To all whom it may concern:

Be it known that I, lViLLIAM R. TVARREN, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Apparatus forGranulating Blast-Furnace Slag, of which the following is aspecification.

This invention relates to an apparatus for securing a more thorough andcomplete contact between a solution in the form of spray and theparticles of molten slag when. thrown from the surface of a granulatingdrum.

' This invention is set fort-h in the following specification and claimsand illustrated in the annexed drawing in which Figure 1 shows alongitudinal vertical section of an apparatus embodying this in vention.Fig. 2 is a vertical transverse section' along the line a: 00 Fig. 1.

This apparatus comprises a housing a.

.An opening or chute as indicated at I) gives entrance intothe housing.In this housing are a rotating protecting sleeve 0 audit shaft (Z. Therotary drum or its hub e is mounted on shaftal. The drum has suitablelongitudinal corrugations at f on its surface. Between the longitudinalcorrugations are openings or slits through the wall of the' drum,through which solution is thrown by centrifugal force whenadmittedthrough intake pipes 7:. Suitable faces are shown at g which are placedat suitable angles or incline. These faces have each one or more out-letorifices h. A suitable .number of supply tubes are indicated at i and7c. Slag or material delivered from entry I) to the rotary drum isbroken up into particles by the rotation or centrifugal force of thedrum. Solvent delivered through the supply tubes 2' and I: and passingout from the slits or orifices is sprayed bythe rapid rotation of thedrum and attached faces and scattered in a spray and comes in contactwith the particles of slag thrown from the drum. The rotation of thedrum 6 and-of the faces g thereon can be effected by any suitablemechanism. A suitable communication allows the solvent delivered fromtubes 71 .to pass to and outfrom orifices h.

I claim:

witnesses.

body comprising a drum, and face portions having an outlet orifice.

2. A device of the kind described comprising a housing with an entrance,a rotary body comprising a slitted drum and face portions having anoutlet orifice, said faceportions being located at each side of the drumso as to supply solvent to material thrown from the drum. p

3. A device of the kind described comprising a housing with an entrance,a rotarybodycomprising a drum and face portions having an outletorifice, said facepor tions being located at each side of the drum so asto supply solvent to material thrown from the drum and said drum havingcorrugations to project such material.

' 4. A device of the kind described comprising a housing with anentrance, a r0- tarV bod com r1s1n a drum and a face oru l \b tionhaving outlet orifices at suitable angle to supply solvent from eachside to material coming from the drum.

5. A device of the kind described comprising a housing with an entrance,a rotary body comprising a slitted drum, and aface portion having outletorifices, said face portion having the outlet portion suitably directedto cause material coming from the drum and material from the'outlets tocome effectively into contact.

6. A device of the kind described comprising a housing with a chute, arotary body comprising a drum, and a face portion having outlet orificescombined with a rotating sleeve containing supply tubes for solvent andhaving communication with the outlet orifices.

7. A device of the kind described comprising a housing with an entrance,a rotary body comprising a drum, and face portions having annular outletorifices beyond the diameter of the drum.

Tn testimony whereof I have hereunto set my hand in the presence of twosubscribing WILLIAM R. WARREN. \Vit-nesses WVM. E. W'AnLANn, CHRISTIANOLMSTAEDT.
